摘要： Viruses have evolved diverse strategies to evade the antiviral response of interferons (IFNs). Exogenous IFNs were applied to eliminate the counteracting effect and possess antiviral properties. Caprine parainfluenza virus 3 (CPIV3) and bovine parainfluenza virus type 3 (BPIV3) are important pathogens associated with respiratory diseases in goat and cattle, respectively. To explore the feasibility of type I IFNs for control of CPIV3 and BPIV3 infection, the activated effects of IFN-stimulated genes (ISGs) and the immunomodulation responses of goat IFN-alpha were detected by transcriptomic analysis. Then, the antiviral efficacy of goat IFN-alpha and IFN-tau against CPIV3 and BPIV3 infection in MDBK cells was evaluated using different treatment routes at different infection times. The results showed that CPIV3 infection inhibited the production of type I IFNs, whereas exogenous goat IFN-alpha induced various ISGs, the IFN-tau encoding gene, and a negligible inflammatory response. Consequently, goat IFN-alpha prophylaxis but not treatment was found to effectively modulate CPIV3 and BPIV3 infection; the protective effect lasted for 1 week, and the antiviral activity was maintained at a concentration of 0.1 mu g/mL. Furthermore, the antiviral activity of goat IFN-tau in response to CPIV3 and BPIV3 infection is comparable to that of goat IFN-alpha. These results corroborate that goat IFN-alpha and IFN-tau exhibit prophylactic activities in response to ruminant respiratory viral infection in vitro, and should be further investigated for a potential use in vivo.
